Universal slot machine 50 code
« on: February 09, 2016, 10:19:41 PM »
I have a universal model Y90 double jokers wild machine. The things i am having problems with is. The 50 error code (door open) stays on the machine all of the time. It will not clear. I can shut the door and put quarters in the machine and push the spin button or pull the handle. The reels will spin and stop. If it hits a win it will pay it in credits. I can play it like this forever with the 50 error code on the machine the whole time. Any time i ring up credits and hit the cash out it just clears them. I read where if there is a 50 code you have to play a game to clear it and that you will not actually win if you hit something. I guess that is why it will not pay out coins is because it is not a real win. I need to know what will cause the 50 error code to stay on all the time. I also noticed that all sounds work accept the reel spin sound. I also need to know what would keep the reel spin sound from working. The sounds i know work. Coin in, reel stop, win, door open tone every 2 minutes door open or closed even when playing the game. I would appreciate any help. I also have a sensor of some kind hanging from the door. I will try to post some pics.

the door open "50 code"  could be caused by the door lock switch not working, or the white cherry switch not working or being mis-wired.  there are a red and green button located on the meter panel, right side of the reel bundle,  with the door open ,you should be able to press one of them and put a credit on the machine, the other will take you through the test menus.  these buttons only work with the door open,  the white cherry switch is a three way switch, pushed in (as when the door is closed) and pulled out with the door open are the same position. middle position (idle) when door open and the plunger in neither in or out.  Idle position is when you should be able to use the test buttons, not either of the two other positions. If this switch is working correctly then the lock door switch is probably causing your problem. 

the sensor you pictured is one of two IR optics,  there should be an upper set right under the coin comparitor, and a lower set that is mounted to detect coins going to the over flow chute, that is probably the set that is in your picture.

Hope this helps

Alright, now your going to get me off my butt!! I have two older Uni's. One is Double Jokers Wild and the other is a standup machine with Midas Touch in it.
When I moved to Laughlin last September the Midas Touch started doing the same thing! Error code 50 never goes away, yet the machine still plays. That's not right! I was thinking it was one of the many doors in the machine, but now you have the same problem so I'm thinking it's either a board or software problem.
Machine should not play if error 50 is active. Or, machine plays and error 50 goes away. Not machine plays and error 50 persists.

I will now dig a little bit and figure it out.

PM me with an email address and I can get a manual to you.

Quick update before I head out for dinner.

Swapped boards in my machines and problem stayed at the machine. So not a board problem. Next logical choice is an optic problem.

In your pic of the grey optic I need to know where it goes. Should be two below coin comparitor, a third further down, and one in the door itself. Suspect yours was the third one down.

The one in the door is the suspect optic.
That third one down below the comparitor is used when coins are diverted to a cashbox in the stand instead of going to the hopper. Only needed for casino use this optic can be used as a spare. Try swapping it with the door optic.

Off to dinner, will continue troubleshooting my machine later.

I would say that is the door lock sensor.  it should be mounted  so the action of opening and closing the lock bar slide would slide in between the "U" shaped optics, that would signal the cpu that the door is closed and hopefully make the code 50 go away.  I'll look at my Mustang machine tonight and see how it is mounted, some earlier machines had a switch positioned there and an arm would hit the switch and preform the same action the IR optics do.

Ok, now I see why your asking about the optics. Your coin optics I have not seen before. Universal used grey or black optics, but the black optics did not look like those. But they are working so no big deal.
First a question; I am assuming the machine was working normally and then started flashing error 50. Right?? NOT, I just got it and it has this problem.

That grey optic hanging looks a little big for a door optic, but might have been rigged that way. Try a piece of elect. tape in the optic. Tape it thru the middle of the U.

My machine problem is a Cherry Switch. This machine has five cherry switches! Much different than your upright machine which should have just one.

Below is a pic of a standard Uni machine door. You can see the grey optic in the door where the lock is. Closing and locking the door blinds this optic telling the mpu the door is closed and locked.

Thanks guys, This machine has been like this since i got it. It never has worked correctly since i have had it. Here is a pic of machine with door open. It has two of the white cherry switches. I guess that is what you are calling cherry switch. The one hanging out is a new switch i put in. I just dont know if the wiring is right on either one. Also i dont know if this machine is suppose to have a door optic. I dont know if the manual will show how they are suppose to be hooked up or not. Do you know if all of the wiring on these switches would be normally open with door open and closed with the door closed?

I took a picture of the mustang machine I have.     it looks like the door lock optic.     the top picture is door open, no black metal in  optic,  bottom picture is door lock closet, black metal blocking optic.  Jim

It is my door sensor. I found out that the 2 door switches have to be made first. Then make the door sensor and it works. Jim your machine looks like mine inside. Could you take any pics that would show how the sensor is actually mounted in there? I think mine is missing what the sensor is suppose to mount to. I guess i can make something. Pics of how it was originally would be nice.  Thanks

the top picture in reply #14 shows exactly how it is mounted. a screw is secured to the door panel, look and you will see the screw, its reddish in color.  that's as good as picture as I can get. the sensor is mounted with the "U" opening up, the screw is put in the bottom plastic .

Ok i made a bracket. What ever is in your machine to mount it to is not in mine. All that is in mine is the outside of the door. I could not put a screw through the door. Here is a pic of mine before i made a bracket. Now my issue is the hopper pays to many coins every time and i get a 31 error code. I also have no sound when the reals are spinning. I think all other sounds work. Any ideas? Thanks

You can blind the optic with tape if it cannot be mounted. My Double Joker has no lock so I tape mine. Then only the Cherry switch signals an open door. I'm betting only one of your switches has wiring?

The hopper overpay is usually caused by a sticky solenoid the releases the coin deflector. You need to take the cover off and spray the solenoid with WD40. Also check the spring.

Your reel spin sound may not be there. Take a picture of your sound chip(s) and I can tell if it has reel spin sound. Not all have reel spin sound.

Also a pic of the eight dip switches on the daughter board at location 1A on the mpu.

I could not just blind the optic on mine. The two switches on door do have wires to them. Those two switches have to be closed or made first and then the door optic or it will tilt. If you just have door open and make the door optic with out the door switches being made it will tilt. So my machine sequence has to be two door switches then door optic. Here is a pic of bracket i made. The optic is screwed to this bracket i made and put in.
